No. 1 was U.S. Rep. Darrell Issa. The California Republican's
reported net worth was $355 million in 2012. U.S. Rep. Michael McCaul, R-Texas, came in second with $101 million, while Sen. Mark Warner, D-Va., was third with $88.5 million.

Republicans edged out
Democrats for the third year in a row, occupying 29 of the 50 slots, The Hill reported. Representatives
outnumbered senators by almost 3 to 1: 37 congressmen and -women to 13
senators.

The Hill came up with its rankings
using financial disclosure forms covering the 2012 calendar year. The reports provide value ranges instead of exact figures, it said, and are likely "conservative estimates of a lawmaker's worth."

In 2012, Upton's net worth was $8 million, according to The Hill.

"The
congressman is the grandson of one of the founders (of) Whirlpool and holds at
least $1 million worth of stock in the company with his wife, Amey. But the
majority of Upton's fortune is in family trusts worth at least $5 million that
are not directly under his control," writes Megan Wilson of The Hill.

Together, the couple hold at least $250,000 in Pepsi stock,
while Amey Upton also has assets in companies including AT&T, Exxon Mobil,
General Electric and Pfizer. Upton
has two liabilities, the Hill reported: a home mortgage worth at least $250,000
and a home line of equity valued at a minimum of $15,000.
